I'm sure threads like this have been posted a thousand times but.... I just picked up a 79 that has been worked. I had a 78 in the family YEARS ago and I did own a 78 again years ago but it had issues and I was young and off it went. Now this is the first 1500 I have dealt with and now that I have it home, the tranny is leaking pretty bad. It does sound nice, no valve noise and surprisingly rust free. I think it sat a lot, but it does pop out or reverse readily. So, my question is, do I pull the thing apart this winter and rebuild the tranny and while I'm in there lighten the fly wheel throw on a header and hope for the best or save the money and go for a K20? I would not wreck the 1500, I'd throw a blanket over it and one day tinker away at it. I have rebuilt transmissions before but not an X, so I'm wondering if it's worth while. What are the chances there is irreparable damage ? That is my main concern. Digging in and finding it pooched. My original plan was just driving it the rest of the year until I have to tow it home and over the winter try to do the K20 but that Fiat sound is sooooo tempting. Also the DPO has swapped the carb but he spoke a different language and it was really hard to get things straight. I'll post a pic when I can get one and maybe send a donut to the first to get it right!
